when u mouse over the content the picture is supposed to change, but it doesnt
heres the js

function menuimage(food)
{
document.getElementById('menuimage').src=food+".jpg";
}
window.onload = function () 
{
    document.onmousemove = function (e) {
        e = e || window.event,mse=Mse(e);
        var img = document.getElementById('menuimage');
        img.style.left = mse[0]+17+"px";
        img.style.top = mse[1]+"px";
    }
}
function Mse(e)
{
 if (window.event){
  var docs=[document.body.scrollLeft,document.body.scrollTop];
  if (!document.body.scrollTop)
  {
   docs=[document.documentElement.scrollLeft,document.documentElement.scrollTop];
  }
  return [e.clientX+docs[0],e.clientY+docs[1]];
